<MockProvider />

function MockProvider({
}: {
children: React.ReactChild;
results: Fixture[];
}): JSX.Element;


is a simple substitute provider to prefill the cache with fixtures so the 'happy path' can be tested. This is useful for storybook as well as component testing.

Deprecated: Use \

instead as it also supports imperative fetches like create and update.

Note: \

disables dispatches, thus no fetches will occur. To simply initalize the cache, use mockInitialState() to construct initialState for the normal \



interface Fixture {
request: ReadEndpoint;
params: object;
result: object | string | number;

This prop specifies the fixtures to use data from. Each item represents a fetch defined by the Endpoint and params. Result contains the JSON response expected from said fetch.



Renders the children prop.
